Geosync is probably the highest unloaded latency, but add in a little bufferbloat and you can easily get way more latency...I've definitely seen a minute+ pings on a plane, which is almost all queuing. I assume airplanes are not the only place with such horrendous queuing, even if most networks have done a good job at reducing that nonsense over the last decade.
I think if you eliminate packet loss and intermittency as a source of increased latency, geostationary satellite is probably as bad as it gets from a transport medium that is stable but just physically limited. 600ms is just about what you would see here. I have seen subsea deliver as high as 450ms, but this purely a function of distance traveled, e.g., Cape Town to Auckland via Hong Kong, for example. Mark.
